This is a replacement 16 tooth 0.6 module motor pinon for the Align 500 line of helicopters. This pinion works best when used with 4S Li-poly packs. With 100% throttle curves it will produce headspeeds about 1950 - 2200 rpm.

Includes:

(1) 16 tooth pinion gear

Note:

Align does not recommend exceeding 2650 rpm on the T-Rex 500

A 4x4mm set screw is required to secure the pinion to your motor shaft and is not included. We recommend using part# PTK-H-4100.
